Hello,
I have a snippet of code below which demonstrates a problem that I'm having
Inspector inspector = new Inspector();
inspector.Load(featurelayer, oid);
Debug.WriteLine("Old: " + GeometryEngine.Instance.ExportToWKT(WKTExportFlags.wktExportDefaults, (Geometry)inspector.GeometryAttribute.CurrentValue));
inspector.GeometryAttribute.CurrentValue = GeometryEngine.Instance.ImportFromWKT(WKTImportFlags.wktImportDefaults, "geometry", featurelayer.GetSpatialReference());
editOperation.Modify(inspector);
await editOperation.ExecuteAsync();
if (editOperation.IsSucceeded) {
inspector = new Inspector();
inspector.Load(featurelayer, oid);
Debug.WriteLine("New: " + GeometryEngine.Instance.ExportToWKT(WKTExportFlags.wktExportDefaults, (Geometry)inspector.GeometryAttribute.CurrentValue));
}
The original geometry of the feature is:

As you can see the difference between the 2 geometries is very minimal, mostly after the 6th decimal places for some vertices. The spatial reference in this case is the WSG84 space, unit is degrees. After this snippet was run, the debug on line 10 printed out the geometry as it was originally - the edit operation did not update the geometry.
If I changed the updated geometry by removing 1 vertex, then the edit operation worked, it printed out the new geometry on line 10.
So my questions are:
- Obviously is there anything stupid that I've done in the snippet above? This is trying to provide a reproduction case - in the real code I don't need to do line 7-11, just move on to something else.
- If not, why did it not work with the geometries I used?
Thank you for your time.
